Failure of these low bluffs may have involved liquefaction.Superficial slides along Eagle River east of Eagle River Loop Road. 2.5. Only List Earthquakes Shown on Map . This earthquake is perhaps most similar in setting to the magnitude 6.8, 2001 Nisqually earthquake, which occurred near Seattle, and caused between 1 and 4 billion dollars in damages.Debris avalanches on bluffs composed of glacial outwash sediment along the Eklutna River. Magnitude 3 and above are large enough to be felt. Main scarp of slump/flow slide at Potter Hill. Debris avalanches on bluffs composed of glacial outwash sediment along the Eklutna River.Complex earthflow slumping along Alaska Railroad overlooking tidal flats along Knik Arm near Mirror Lake. The number of aftershocks will drop off over time, but a large aftershock can temporarily increase the numbers again. Severe shaking was reported throughout the entire island, while strong shaking was Suffering the worst damage was Vine Road, a section of which buckled and became impassable. We document observations that point to future directions of research and hazard mitigation. These cracks occur at the top of a steep valley wall on the south side of Potter Creek in south Anchorage.
For the most up-to-date information, please visit the USGS event page, and for estimates of casualties and damage, visit the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) website. Ground failures are unlikely to recur after the mainshock, but aftershocks greater than about magnitude 6 could reactivate existing failures or cause new failures in ground that was weakened by the mainshock.Ground cracks present the potential for future slope failure during aftershocks or heavy rainfall. What makes an earthquake "significant"? Cracks may form in the ground and the ground may move horizontally, known as lateral spreading. For the most up-to-date information, please visit the U.S. Geological Survey scientists continue to investigate the Lateral spreading disruptured Vine Road near Wasilla. The earthquake's epicenter was near Point Mackenzie, about 10 miles (16 km) north of Anchorage, and occurred at a depth of 29 miles (47 km). Many failures of engineered materials occurred on or adjacent to saturated lowlands filled with organic sediment, silt, or sand.Ground cracks present the potential for future slope failure during aftershocks or heavy rainfall.
These cracks occur at the top of a steep valley wall on the south side of Potter Creek in south Anchorage.If you felt this earthquake, report your experience on the For information about tsunami watches, warnings or advisories, visit the The USGS operates a 24/7 National Earthquake Information Center in Colorado that can be reached for more information at 303-273-8500. In this photo, USGS scientist Peter Haeussler points to a dark layer at the top of a sediment core taken from the floor of Eklutna LakeLandslide from bluff below rail grade north of Rabbit Creek. "Even as we recover from the impact this event had on our families, friends and neighbors, USGS is leading post-earthquake surveys and investigations,” said Aimee Devaris, USGS regional director for Alaska. Detailed earthquake information - overview map, magnitude, time, depth, information source, shake map, list of reports. Shaking from the earthquake was felt strongly in the prefecture and the nearby metropolitan areas of Osaka and Kyot… Our research provides objective science that helps stakeholders prepare for and mitigate the effects of future earthquakes and tsunamis, which bolsters the economic health and well-being of Alaska and the...Below are publications associated with this project.Jibson, R.

On 18 June 2018, around 7:58 a.m. Japan Standard Time, an earthquake measuring 5.6 Mw on the moment magnitude scale struck in northern Osaka Prefecture, Japan.
In addition, Matanuska Electric Association reported that 46,000 customers were left without electricity immediately after the earthquake.Overall, damage in Anchorage was estimated to be at least US$30 million, including $10 million to repair pipes, and $10 million in public facilities.A federal disaster was declared shortly after the earthquake and the
